Mains pressure cold water and tank hot water mixer tap

My son has just bought a flat and all the cold water is mains pressure and the hot water from a tank in a cupboard next to the bathroom heated by an immersion heater on economy 7.


The flat is all electric.


The bath has a mixer tap with a shower attachment and of course there is no way to balance the hot and cold water to have a shower, the hot water pressure does not keep the diverter knob up to make the water run through the shower hose on its own.


Then when the cold water is turned on the shower just runs cold.


Cold water pressure is quite strong.


Also the cold water pipe runs along the bath, half way up, hidden by the outward curved bath panel.


I suggested he get an electric shower but he would have to get a new consumer unit as his flat still has fuses and fuse wire.


Is there a way to reduce the cold water pressure just to the bath tap?


He did try turning the stopcock down but then it took ages for his toilet to fill.

    Try fitting a pressure reducing valve in the cold feed to the bath tap.

    New team used to sell a pressure equalising valve which would reduce the cold down to the hot water pressure. Not sure if they still sell them though.

    Deva now supply them. These could be supplied by most independent plumbers merchants.

    I'd fit a pressure reducing valve on the cold, as the others suggested, and also getting a new thermostatic mixer tap with shower.

    Turning the stopcock (all one word) down does not reduce pressure, it reduces flow.

    Others have suggested pressure reducing valves, I have no experience of these. I have resolved the problem previously by taking the bath cold water from a tee on the feed to the hot water cylinder.
    You might as well ask the Wizard of Oz to give you a big number as pay a Credit Referencing Agency for a so-called 'credit-score'
